Apple Pencil 2 causing Car Key Fob not to work

Hello!

I'm having a weird issue. Whenever I leave the Apple Pencil 2 connected (magnetically) to my iPad Pro 11, my car keys don't work. My car keys connects wirelessly to the car, meaning that it uses the push start button. When the Pencil is attached, I cannot start the car. However, when I remove the pencil, I can start the car. I believe when the Pencil is connected, it is causing disturbance to the wireless key. Anyone having the same problem? Any suggestion on how to fix this?
